    From the review of the latest monster Denon AVC in the current Hi-FI News I was worried to see that they measured a huge amount of jitter in the multi channel digital audio transferred into the AVC using HDMI v1.1 (the version the digital audio support, as opposed to v1.0 which is digital video only). I was looking forward to HDMI v1.1 being a new gold standard in AV interconnects, but from this measured performance you'd be better of leaving HDMI to handle video only. Does anyone have any clue if this poor measurement is down to bad implementation (which would be somewhat surprising in Denon's top dollar stuff), or is it inherent in the HDMI technology?

    Not sure if it's inherent for HDMI as there isn't a lot of other stuff around that you can compare it to at the moment (in terms of AV Amps etc). At least on the Denon you have multiple options such as Denon Link, Firewire and digital optical and coaxial. The Denon includes a function which reduces jitter on the Firewire links. Denon Link is jitterless. :)

    Great idea but proprietry. There is no reason why HDMI audio should be jittery. Poor design most likely.

    Poor design doesn't seem to be "compatible" with that £4000 lump. I personally conclude that the HDMI technology is bad, or Denon deliberately 'broke' it in order to demonstrate the superiority of their proprietary solution. This is of course predicated on the assumption that the Hi-Fi News measurement was accurate.
